Tarlov Cysts in a Woman With Lumbar Pain.

A 25-year-old woman presented to her primary care physician with thoracic spine pain; two weeks later, she returned to her primary care physician with lumbar spine pain that limited exercise and sitting for 30 minutes or less. The patient was referred to physical therapy for examination, then referred back to her primary care physician after complaints raised concern for a mass or other source of neurologic compression. Magnetic resonance imaging was performed and revealed 4 sacral perineural (Tarlov) cysts. J Orthop Sports Phys Ther 2018;48(2):121. doi:10.2519/jospt.2018.7644.
